Filed Apr. 12, 1963, Ser. No. 272,61@ rs Claims. (ci. 22a- 17) This application is a continuation-in-part of my copending U.S. patent application Serial No. 48,033, filed August 8,1960, now Patent No. 3,085,732.

This invention relates to cartons and similar types of containers with pouring and dispensing spouts, used in the packaging of substances which are susceptible of being poured through such dispensing spouts.

It more particularly relates to an improved form of a dispensing and pouring spout which is an integral part of paper or paperboard cartons and similar containers.

The principal object of this invention is the provision of an improved dispensing spout construction in a carton of the character described above which has marked advantages over prior art pouring spouts from a constructional and utilitarian point of view.

It is an object of this invention to provide in combination, a carton and pouring spout which may be assembled with greater efficiency and facility. This efficiency is achieved by virtue of the design of the carton and spout of this invention which enables said spout to be formed in all respects at the place and at the time the carton is being die cut and prior to shipment to the party that assembles and fills the carton. This is made possible by the fact that the spout can be formed in all respects prior to assembly of the carton and the fact that the carton can be shipped flat after the spout is formed. Spouts of the prior art had to be formed at the time and place where the carton was assembled because certain necessary operations in their formation could not be done until the carton was assembled and because they could not be economically shipped after assembly. Such spout formation at this point of carton assembly requires machinery and operations which make such prior art spouts impractical from an economic standpoint.

It is another object of this invention to provide aA carton having a pouring spout as an integral part thereof which is prevented from inadvertently entering into the interior of the carton.

It is another object of the invention to provide a carton having a pouring spout integral therewith and having additional portions for strengthening the support of the spout with respect to the carton.

It is an additional object of the invention to provide a carton blank having an integral spout which can be formed with a minimum of waste.

A further object of the invention is to provide a carton blank having an integral pouring spout adjacent to the top portion of one side wall thereof and being adapted to augment the support of the portion of the top of the carton adjacent to the pouring spout.

These and other objects of this invention will become apparent from an examination of the drawings, in which:

Referring now to FIGS. 1, 2, 3, 4 and 5, the number 20 refers generally to a carton which may be made in any desired size and of any conventional material. The particular carton blank 26a shown in FIG. 5 has two wide sidesr21, 22 and two intermediate narrow sides 23, 24 alternately disposed. When the box is assembled as depicted in FIG. 1, the narrow sides are in parallel planes opposite each other, and are perpendicular to the two large sides 21, 22 which are also disposedl in opposing parallel planes. The flap 2S, adjoining side 23 overlaps the wide side 22. Said flap 25 is used to afiix side 23 to side 22 when the carton blank 20a is assembled. Usually an adhesive material is placed on flap 22 which will effect a seal, but other convenient means for afxing flap 25 to side 22 such as stapling may be used.

Each of the respective sides of said carton blank 29a have flaps hingedly attached to each of said sides. Thus, said carton blank Ztla, has two large flaps 26, 27 and two small aps 2S, 29 disposed as indicated on sides of corresponding lengths: flap 27 adjoins side 22, flap 28 adjoins side 24, liap26 adjoins side 21, and flap 29 adjoins side 23. Large flap 27 is provided with a flap Sil to which an adhesive material is applied, and which is used to affix said flap 27 to side 23 when said carton blank 20a is assembled.

The flaps 26, 27, and 28 are folded over, in the usual manner when the box is assembled. Flap 28 is folded over rst, then flaps 26 and 27 are folded over, to lie in a common plane superimposed on flap 28. Thus, in the assembled carton 20, the flap 28 is at the bottom, over which flaps 26 and 27, respectively, are superimposed and affixed together wtih conventional adhesive means. Flap 29 is folded down into the plane of side 23 and attached thereto.

A pouring spout iiap 31 is cut out of ap 26 before assembling carton blank 2da. In the embodiment shown in FIG. 5, a portion of said spout flap 31 is also cut from said small flap 29. Spout flap 31 is hingedly connected to said small Hap 29 along the hinge -line 32.

Spout flap 31 is scored and bent along lines 33 and 34 forming hinges at those places, which lines thus form and dene side walls 35, 36 of the pouring spout generally referred to as 37. A floor of said spout 37 is situated between said side walls and 36.

Extensions 39 and dll, disposed at the extremes of the side walls 35, 36 are stop members, the function of which will be described below.

Small ap 29 is provided with a rectangular aperture il whose size is equal to that of the floor 33 of spout 37. The location of said aperture all is such that it will be congruent with said floor 3S when said spout flap 33t is bent along its hinge 32 and superimposed upon the outside surface of said small flap 29.

Said spout flap 3l is folded as indicated above. Small flap 29 is folded inwardly along its hinge line 42 and is superimposed upon the interior surface of side 23. Spout ap 31 and small ap 29 are then affixed to side 23 by adhesive or by a staple 29a as shown in FIGS. 1-4.

Side 23 is provided with a rectangular wall aperture 43 in juxtaposition with the aperture il and the iloor 3S of the spout 37. Integral with side 23 and cut from the aperture 43 is a cover flap rtl4 fitting in said aperture 43. Flap 44 is hingedly connected to side 23 along hinge line 45. Flap Il@ may also be provided with an integral tab du which the `operator may use to open the ap t4 without interfering with the complete closing of the flap lift when the spout is not in use.

The floor 38 of said spout 37 is aflixed to the cover tap 44 by adhesive or by staple 37a shown in FlGS. 1-4. The size of the cover flap 44 is somewhat larger than that of aperture 41. This will prevent an operator pushing the Hap cover 44 into the box, which would render the pouring spout inoperative. This also serves to seal all sides of the spout when in closed position.

In order to operate the spout, one grasps the tab to and pulls the flap 44 and spout 37 outward to its fully-outwardly disposed position, which places the spout at an angle of approximately 90 from its closed position and presents the maximum opening that is possible with the closure out of the path of the opening. The extensions 39 and 4t? of side walls 35 and 36 are stopping members which engage the top rim of the aperture t1 when said spout is in its fully opened position. Said extensions 39 and 40 thus prevent one from pulling the spout 37 entirely out of the carton 2t?, rendering it inoperative.

The salient feature of this embodiment of the invention is that the spout 37 may be cut out, bent and atiixed to the small flap 29 and to the cover ap 44 prior to the assembling or setting up of the carton 2b. This makes it feasible to form the spout subsequent to cutting the carton blank but prior to shipping this blank flat to the party who assembles and lills it. This vastly improves the overall assembling process, and results in greater speed, efficiency and economy in the overall production and use of cartons. Further, the spout is formed from within the contines of the blank thus economizing on material.

Referring now to FIG. 6, a modification in the design of the primary embodiment of the invention is depicted. In this design the spout flap Stb is cut entirely from the large flap Zub. The extension members 3% and dbb arel of a slightly different configuration. The carton blank Ztlb is assembled in the same fashion as that of carton blank 20u of the primary embodiment described above. The extension members 39b and dllb function by camming against the rim of the aperture ilb, preventing further opening of the spout 37b when it is approximately 90 away from its `closed position. The cover iiap 4b of this modication has a tab 6b which is hingedly connected and tits into said llap Mb as indicated in FIG. 6.

Referring to FIG. 7, `another embodiment of this invention is depicted. The carton blank Sti has conventional configuration: two large sides 51, 52 and two small sides 53, 54. alternately disposed, together with flaps 55 and 5o to which an adhesive is applied and which serve to hold the assembled carton together. Flap 55 joins side 54 to side 52. Flap 56 joins side 54 to flap 57. l-lingedly adi joining each side are large flaps 57, 58 and small flaps 59 and 6b.

The terminal portion of small flap titi is cut to form a spout liap 6l. Hinges 6?., o3 of said spout fiap 6l are fashioned by scoring and bending along lines o2, 63. A. spout 64 is thus formed from spout flap till and comprises two side walls 65, 66 and a lloor 67. Extension members 6%, 69 are formed at the extreme corners of the side walls d5, 66.

A score line is made at 69 and 70. The entire spout flap til is folded along line 7@ and is superimposed upon the outer surface of said small fiap 60. A rectangular aperture '7l is cut in said small flap ot?, in juxtaposition with the floor 67 of said spout o4 and congruent therewith.

The small tiap 6b is folded inwardly and is superimposed upon the interior surface of side 5d. The small flap 6) is affixed to side 54.

Side 54 is provided with a rectangular wall aperture 72 in juxtaposition with said floor o7 of said spout 64 and said aperture 7l. Wall aperture 72 is provided with a cover flap 73 which is hingedly connected to the baser of said wall aperture 72 and said cover flap 73 is affixed to the floor 67 of said spout 64. This cover flap 73 is somewhat larger than aperture 71.

The spout 64 functions in a manner similar to that described earlier with respect to the primary embodiment, the line 70 providing the hinged connection on which line the spout 6d pivots as it functions.

The construction of the embodiment just described permits the afixing of the floor 67 of said spout 64 to the cover liap 73, and the small flap o@ to the side 54 before the carton blank is assembled. As in the primary embodiment, this permits formation of the spout prior to assembly of the carton with its consequent advantages.

n this embodiment flap 56 may be lengthened to cover the spout 64 when assembled to thus provide a seal extending over the spout prior to initial use of the assembled carton and spout.

FIG. 8 depicts a carton blank of still another embodiment of this invention incorporating the constructional and utilitarian advantages described earlier. In this embodiment, the spout titi is cut from the central portion of the small flap 3l. Score lines are made, as shown at S2, 83 and Se. Line S2 defines a hinge upon which the actual functioning of the spout 8b depends. Lines 83 and 84 define hinges which in turn form side walls 85, 86 and floor 87 of spout Sti. Extension members 88 and 39 are formed in spout ist) when said spout is cut from the ilap 8l.

Flap S1 is folded inwardly along line 9@ and superimposed and affixed to side 9i. There is cut in side 9i, a rectangular aperture 92 in which fits a cover flap 93 which is hingedly connected to the bottom of said aperture 92 at hinge line 94. Hinge line 94 is in juxtaposition and parallel with the hinge line 82 of said spout 80, and the aperture 92'. is likewise in juxtaposition with the floor 87 of said spout 3b.

The floor S7 of said spout titl is affixed tothe cover Hap 93 and the carton is assembled in the conventional manner. The cover iap 91 may also be provided with a tab 95 to facilitate opening of the spout Sti. The said spout titl functions in a manner similar to that described above for the other embodiments of this invention and pivots on hinge line 32 from its closed to its fully open position, at an angle of approximately 96 relative to said closed position.

FlGS. 9 and 10 show another feature of the present invention which can be used with any of the embodiments thereof. Referring to FlG. 9 a closure iiap 96 is cut adjacent the large side 52 which, when the carton is assembled, as shown in FiG. l0, folds over and is attached around its periphery to the small side containing the spout to cover the spout and thus seal it prior to use. When the user desires to open the spout for the first time he simply removes the serrated portion 97 in the ap 96 to thus expose the spout for use. Further, in this embodiment iiap 96a replaces flap 56 in the FIG. 7 embodiment and provides for assembling the top of the box in the ordinary manner using flap 96a and 59 in the ordinary manner to support superimposed flaps 57, 58. Still further, if ap 96 is extended the full height of the carton then the carton can be assembled without need for flap 55.

Carton blank 100 includes side walls 101-104 having common foldlines 105, 106 and 107. Glue Hap 103 extends from foldline 109 at side wall 101. End Hap 110 is connected to foldline 10111 of side wall 101 by flaps 11111 and 111b containing foldlines 111C and 11111 (FIG. 11).

End tiap 112 extending from foldline 10211 and side Wall 102 is relieved by the forming of stop flap 114 which extends from foldline 11011 of end flop 110. In addition support iiap 115 extends from foldline 11011 adjacent to stop flap 114. Opening 11511 is formed in the portion of the support ap adjacent to the stop flap.

End flap 116 extending from foldline 10311 at side wall 103 is provided with aps 11711 and 117b disposed along foldlines 117C and 11711, respectively. The remaining end flap of the carton blank, namely end ap 118, extends along foldline 10411 of side wall 104. Flap 119 having tab 120 extending from hinge line 12.011 extends from foldline 11811 of the end flap.

Cover ap 121 is formed from side wall 101 of the carton blank and is provided with hinge line 12111. When the cover flap is opened, aperture 122 is formed in side Wall 101. Edge portion 121k of cover flap 121 is spaced apart from edge portion 12211 of aperture 122 in order to form a slot into which a thin instrument such as a persons fingernail can be inserted in order to swing the cover flap outwardly about its hinge line.

End flap 110 contains spout Hap 123 which includes base portion 12311 extending from foldline 12311 and Wings 123C extending from foldlines 1231i. In addition to base portion 12311, spout flap 123 includes extensionl 123e extending from the base portion.

In erecting carton blank 100, adhesive or glue is applied to portions 110!) and 110C of end flap 110. Support flap 115 is then folded about foldline 11011 and pressed on top of end flap 110 as viewed in FIG. 1l. Glue is then applied to the reverse side of flap 115 from that shown in FIG. ll. In addition glue is applied to the surfaces of cover flap 123, flaps 11111, 111b, cover flap 121, and portions 101b of side wall 101 adjacent to aperture 122. End ap 110 and flap 11111 are then folded together about foldline 111C until they are moved into a position overlying and in engagement with iiap 11111 and side Wall 101.

Glue is then applied to the reverse side of the portion of end flap 110 adjacent to foldline 11011 and stop iiap 114 is folded about foldline 11011 and pressed down upon the glue on end ap 110. At this point the steps necessary for the completion of the blank for the pouring spout is iinished and the blank is prepared for subsequent erection into a carton. Thus if carton blank 100 is folded without the steps of gluing, it would pass `through the transitional state shown in FIG. 12. Since the carton blank can be assembled by gluing alone it `eliminates the problems associated with attempts to staple or otherwise connect the plurality of flaps of the spout arrangement.

FIG. 13 shows the carton in the erected form with ap 119 glued in place with respect to rside wall 101. Tab 120 which is not glued `overlies extension 123e of the spout flap. As shown in FIG. 14 flaps 11111 and 111b are glued together along their adjacent surfaces and are folded in such a manner as to be doubled. A similar arrangement is provided by aps 11711 and 117b at the opposite end of the carton. The doubling of the flaps provides a cantilever-like support for each end of end j 6 flaps 112 and 118 with the result that the carton has increased crushing strength in the vertical direction. Moreover the double folded flaps provide the further advantage of providing a good supporting foundation for end flaps 112 and 110 during the handling thereof. Either of end aps 112 and 118 can be folded lirst into engagement with doubled flaps 11111, 111b, and 11711, 11711 during erection of the carton. For example, if it is intended that flap 119 be not employed, end ap 113 can be initially engaged to the doubled flaps to insure a tight seal at both ends of the carton.

As shown in FIG. l5 prior to opening cover flap 121 it is necessary to raise tab 120. Upon lowering cover ap 121 base portion 12311 is simultaneously lowered since the two parts are glued together (FIG. 16). During lowering of the spout, wings 123C engage the adjacent edge of stop ilap 114 and thereby oppose and ultimately terminate the downward travel of the spout with respect to side wall 101.

As shown in FIG. 16 it can be seen that the gluing toget'ner of base portion 123e and cover flap 121 provide a double wall of increased strength for the spout. Foldline 123]) as shown in FIG. 17 can be provided with one or more cuts 1231 extending therealong in order to weaken the foldline but to give it sufficient strength to remain assembled during fabrication of the blank and erection of the carton. Upon initially opening the spout, the uncut portion of foldline 123]c is substantially severed with the result that the spout is primarily supported by hinge line 12111 at cover flap 121. The severing action reduces the restraint applied to the spout so that it can remain open when desired and yet be subsequently fully closed.

In a similar manner, hinge line 12011 of tab 120 can be provided with one or more cuts 120b in order merely to reduce the resiliency of the hinge line once the tab has been raised but the cuts are not sucient to sever the tab from iap 119.

It can be seen in FIGS. 16 and 17 that upon closure of the spout, cover iap 121 adjacent to its edges comes into contact with the mating portions of end flaps and support fiap with the result that the spout is retained from being inadvertently pushed into the interior of the carton. The engagement of extension 123e with stop flap 114 assists in accomplishing this function. Following closure of the spout, tab can be folded doWnwardly over edge portion 12111 of the cover fiap in order to retain the spout in the closed position.

It should be understood that side wall-s 101 and 102 and the arrangement of end ap 110, end ilap 112, stop flap 11d, and support flap 115, etc. need not necessarily be positioned adjacent to the left of side Walls 103 and 1041 as shown in FIG. ll. Thus the carton blank can be revised with side walls 103 and 104 and their related end flaps, etc. being positioned to the left of Walls 101 and 102.

1n preparing blank 100, the blank can be cut from a strip of paperboard or the like extending in the direction of foldlines 10S-107. The portions of end ap 110 extending beyond the edge of the blank defined by end iiaps 112 and 118 as well as sup-port ap 115 can be cut from the end flaps of the adjacent blank which are disposed at the end of the blank opposite to the pouring spout. Thus, for exampie, with the pouring yspout being disposed adjacent to the top portion of a blank, it would cut in part from the bottom end flaps of the adjacent blank. In this way, Waste of paperboard is substantially eliminated.

It will be appreciated that the spout of this invention can be formed in the large as well as the small side of the carton in the same manner as described above if the manufacturer desires such a spout piacement to permit a larger size thereof or for any other reason. It will also be appreciated that the spout in the assembled carton may be sealed with an ordinary wax paper overlay to prevent the penetration of contaminants prior to tirst use.`
